    Abstract: The disclosed technology provides solutions for generating accurate virtual representations of real-world environments. A process of the disclosed technology can include steps for: aggregating a plurality of images, wherein each of the images is associated with a set of geolocation coordinates, extracting a set of image parameters from the plurality of images, wherein the set of image parameters includes a dynamic range value, and providing the set of image parameters to a three-dimensional (3D) modeling platform. In some aspects, the process can further include generating a virtual environment corresponding with the set of geolocation coordinates, wherein the virtual environment is based on the set of image parameters. Systems and machine-readable media are also provided.
